Planet, your sitch is still pretty young. Don't get discouraged yet. And don't convince yourself that you've got nothing to offer your W, she was attracted to you enough to marry you so get back in touch with that guy she fell in love with 6+ years ago. There's a book called Married Man Sex Life Primer that can be crude, but does help men to get back in touch with what makes us men- our alpha qualities. It might help you to read it. One of the things he talks about in the book is your wife married you, so that automatically gives you a leg up on the competition because clearly you are someone she found very attractive in the past. You need to be THAT guy again, not the sad, desperate, clingy LBS that so many of us are after BD.
